Help with digester!

[Marco Mistroni <mm...@waersystems.com>]

Hi all,
	I am experiencing problem with digester when I use
The xml files for the rules.

I have following SQL file :

<?xml version="1.0" encoding="UTF-8"?>
<sql>
  <statement>
     <name>getUsers</name>
     <value>select * from user_details</value>
  </statement>
  <statement>
     <name>getContact</name>
     <value>select *  from contact WHERE contact_ref = ? </value>
  </statement>
</sql>

I want, for each statement, to populate an Hashtable with name as key
and
Value as index.

When running normal digester and setting rules in java code
digester.addObjectCreate("sql", java.util.Hashtable.class);
			digester.addCallMethod("sql/statement",
"put",2);
			digester.addCallParam("sql/statement/name", 0);
			digester.addCallParam("sql/statement/value",1);
		} catch(Exception e) {

the problem is that either I don't know how to do the same in an xml
file
or my xml file for rules is incorrect.
I have tried with the following

<?xml version="1.0"?>
<digester-rules>
  <pattern value="sql">
      <object-create-rule classname="java.util.Hashtable" />
	   <set-properties-rule />
	   <call-method-rule pattern="statement" methodname="put"
             paramcount="2" />
              <call-param-rule pattern="statement/name"
paramnumber="0"/>
              <call-param-rule pattern="statement/value"
paramnumber="1"/>
     
  </pattern>
</digester-rules>

can anyone help?

Thanx in advance and regards
	Marco

It looks like everything is ok.
Look at the logs and see what's happening.
Maybe some problem with the arguments types. Try the method 
addCallMethod(String pattern, String methodName, int paramCount, 
String[] paramTypes)
and explicitly set the argument types. I've found a similar problem in 
calling ArrayList.add and it is because of the argument being 
java.lang.Object

Good luck.
